In Reply: In response to Dr Wong and colleagues,
in 30 years of clinical practice at the Jiangxi Women's Hospital in Nanchang,
China, we have never found respiratory disease, allergic rhinitis, or asthma
to be associated with moxibustion, which in our experience seems to be harmless
to anyone exposed to it. No patients withdrew from the study for this reason,
and we observed no unintentional burning among our patients.

We found no evidence that moxibustion smoke increases respiratory tract
morbidity in infants in the treated group. However, we are willing to consider
a prospective observational study to follow up the 2 groups of infants.
